Default Dalo Pen replacement

Like many others I've been disappointed with several of the current offerings as Dalo replacements. I have found most, particularly those that are actually "permanent markers" do not prevent etchant damaging (pitting) the wanted copper areas and this is a big problem on very fine tracks. Even the Cif etchant resist pen sold by CPC Farnell is not totally reliable.
I believe I have at long last found a true Dalo replacement - it's called "Pen-touch" and is a paint(not ink) pen. It's available in several widths from Amazon.
I find the fine tip best as it allows the drafting of narrow tracks and larger areas can be filled in if needed. This is a pump action pen with a plastic tip, not just hole at the end of a narrow metal tube. It doesn't run and the paint is quite dense.
Not very expensive either £4.99 including post.
